Abstract

PURPOSE: To generate a 4-parameter restriking voltage matching with the rated requirement and, at the same time, reduce the rising ratio of the restriking voltage by connecting the second voltage source circuit in series to the first voltage source circuit connected to a current source circuit.
CONSTITUTION: To a breaker 6 to be tested of a current source circuit there is connected the first voltage source circuit comprising a serial circuit X of a capacitor 8, a control gap 9 and a reactor 10, and a serial circuit of a restriking voltage adjusting resistor 11 and a restriking voltage adjusting capacitor 12, which circuit is connected in parallel to the circuit X. Between a point B of the first voltage source circuit and a point A of the breaker there is connected the second voltage source circuit comprising a series circuit Y of a closing switch 13, a capacitor 14 and a resistor 15, an auxiliary breaker 16 connected in parallel to the series circuit, and a series circuit consisting of a capacitor 18, a control gap 19 and a reactor 20, which are connected in parallel to the series circuit Y.
